The disconnecting switch adopts double-column centre-open, contact-transferring structure, which has the ability to clean the contacts automatically and improves the contact reliability;
The contact fingers are made of new materials with high strength, high conductivity and high elasticity. Relying on the elasticity of the contact fingers themselves to clamp the contacts, avoiding the current spring corrosion, heat annealing and contact caused by the reduction of clamping force, contact resistance.Avoiding the vicious circle caused by spring corrosion and heat annealing, which reduces the clamping force, increases the contact resistance and intensifies the contact heating.
